UNIX Bash – Domain List Get Whois Info

If you manage a list of domains it’s sometimes helpful to have a script like this to check the information from time to time.

I plan to clean this up in time but for now this works.

First create a text file like below that has domains in it

google.com
yahoo.com
microsoft.com

Then create and run this bash/shell script

#!/bin/sh

#  whois-DomainList.sh
#

# Variables - Start
dt=$(echo `date +%Y_%m_%d_%H.%M.%S`)
sDatedName="DomainListDetails_$dt.txt"
# Variables - Stop

#echo "Domain Information for $1"
#whois $1 | egrep -i 'Expiration Date:|Expires on|Registrar:|Name Server:'

echo "Running Process..."
rm $sDatedName

cat domainlist.txt  | while read line; do
lLine="$(echo $line | tr '[A-Z]' '[a-z]')"
echo "\n$lLine\n" >> $sDatedName;
echo "\n$lLine"
